The relative value of pulmonary artery wedge pressure (PAWP) and right ventricular end-diastolic volume index (RVEDVI) as a reflection of the preload status of the critically ill was determined in 29 patients. Regression analysis of 131 hemodynamic studies demonstrated that cardiac index (CI) correlated better with RVEDVI (r = .61) than did PAWP (r = .42). ⋯ However, all eight patients with a RVEDVI less than 90 mL/m2 responded with a rise in CI, but all seven patients with a RVEDVI greater than or equal to 139 mL/m2 failed to respond. Thus, RVEDVI more accurately predicted preload recruitable increases in cardiac output.

Transthoracic echocardiography is an easily accessible, non-invasive imaging procedure for evaluation and follow-up of critically ill patients. It is particularly helpful in evaluating patients with thoracic pain, low-output syndrome or heart murmur, and has prognostic value in acute myocardial infarction. It makes a diagnostic contribution in 60 to 90% of cases, and has therapeutic implications in 50 to 65%. New ultrasound technics are briefly discussed.

Outcome of intensive care of the "oldest-old" critically ill patients.
To determine the short-term and long-term outcome of critically ill "oldest-old" (greater than or equal to 85 yrs) patients. ⋯ These findings suggest that age alone may be an inappropriate criterion for allocation of ICU resources.

Comparative Study
Prospective comparison of clinical judgment and APACHE II score in predicting the outcome in critically ill surgical patients.
Prospective identification of patients who will not survive has been proposed as a means of limiting utilization of medical resources including critical care. This study prospectively compared prediction of outcome for surgical ICU patients by clinical assessment and the APACHE II score. Five hundred seventy-eight patients were assessed within 24 hours of admission by the ICU attending physician and predicted to live or die. ⋯ Over 40% of patients predicted to die by both methods actually survived. This study demonstrates that clinical assessment is superior to APACHE II in predicting outcome in this group of surgical patients, although the difference is small. In addition, this study suggests that neither clinical assessment nor the APACHE II score, when obtained within 24 hours of admission, is very reliable at predicting which surgical ICU patients will die.

Patterns of sedation and analgesia in the postoperative ICU patient.
Control of pain, discomfort, and agitation is an integral part of the postoperative management of critically ill patients. We examined the sedative and analgesic practices in a surgical ICU during two six-month periods, one in 1986-1987 and the other in 1989-1990. Narcotics, especially morphine and Fentanyl, were the most commonly used drugs. ⋯ The use of midazolam during the second survey period was associated with a reduced dose of narcotics in artificially ventilated patients receiving continuous intravenous Fentanyl and morphine. The use of epidural Fentanyl, especially following thoracic surgery, was greatly increased during the second study period. More work is needed to assess the effects and effectiveness of ICU sedative and analgesic regimens.
